Since the update, when we send an estimate the email says invoice and balance due. Is this an internal adjustment that needs to be made?

It's a known bug. One of many (hundreds?) with the new 'improved' invoices.

I'm here to provide some insights when sending estimates as to why it shows invoice in QuickBooks Online, @carterlandservic.

As per checking, I've found an ongoing investigation (INV-100722) regarding the issue when attempting to send an estimate, but the email states about invoice and balance due.

Please know that our engineers are working to fix the issue as soon as possible. 

With this, I recommend contacting our support team so you'll be added to the list of affected users and receive email updates.

It's clearly a bug, not an "investigation". Just admit it.

Knowing the schedule does not ensure in any way that "concerns" will be "addressed promptly".  Do you actually believe the statements you copy/paste?

I am having the same issue. Now I have to send estimates from my email instead of from Quickbooks which is more time consuming. It seems like with every update with Quickbooks, everything gets worse not better.

Hi there, @Hazel2019.
